Consensus document on the diagnosis and treatment of sexually transmitted diseases in adults, children and adolescents / Documento de consenso sobre diagnóstico y tratamiento de las infecciones de transmisión sexual en adultos, niños y adolescentes

Sexually transmitted diseases (STDs) are one of the most common and universal problems of public health. Human immunodeficiency virus (HIV) and STD infections are clearly interrelated, and share risks, incidence and transmission mechanisms. The aim of this document is to inform health professionals about the current situation and management of STDs, which, because of their relevance, need greater care, both in the general population and in the population with HIV. These guidelines for STD treatment, although clinically oriented and focused especially on treatment, contain other aspects related to assessing and evaluating patients, as well as recommendations for diagnosis

Las infecciones de transmisión sexual (ITS) son uno de los problemas más frecuentes y universales de Salud Pública. La infección por el virus de la inmunodeficiencia humana y las ITS están claramente interrelacionadas, compartiendo riesgos, incidencia y mecanismos de transmisión. El objetivo de este documento es dar a conocer a los profesionales sanitarios la situación actual y el manejo de aquellas ITS, que por su relevancia necesitan una mayor atención, tanto en población general como en población infectada por el virus de la inmunodeficiencia humana. Estas directrices para el tratamiento de las ITS, aunque orientadas desde el punto de vista clínico y centrado especialmente en el tratamiento, también recogen otros aspectos relacionados con la evaluación y valoración del paciente así como recomendaciones de diagnóstico

Sexually Transmitted Infection Testing of HIV-Positive Medicare and Medicaid Enrollees Falls Short of Guidelines.

BACKGROUND: Men who have sex with men with HIV have high sexually transmitted infection (STI) incidence. Thus, the Centers for Disease Control and Prevention (CDC) recommends at least yearly STI screening of HIV-infected individuals. METHODS: We calculated testing rates for syphilis, chlamydia, and gonorrhea among HIV-positive Californians with Medicare or Medicaid insurance in 2010. Logistic regressions estimated how testing for each bacterial STI relates to demographic and provider factors. RESULTS: Fewer than two-thirds of HIV-positive Medicare and fewer than three-quarters of Medicaid enrollees received a syphilis test in 2010. Screenings for chlamydia or gonorrhea were less frequent: approximately 30% of Medicare enrollees were tested for chlamydia or gonorrhea in 2010, but higher proportions of Medicaid enrollees were tested (45%-46%). Only 34% of HIV-positive Medicare enrollees who were tested for syphilis were also screened for chlamydia or gonorrhea on the same day. Nearly half of Medicaid enrollees were tested for all 3 STIs on the same day. Patients whose providers had more HIV experience had higher STI testing rates. CONCLUSIONS: Testing rates for chlamydia and gonorrhea infection are low, despite the increase in these infections among people living with HIV and their close association with HIV transmission. Interventions to increase STI testing include the following: prompts in the medical record to routinely conduct syphilis testing on blood drawn for viral load monitoring, opt-out consent for STI testing, and provider education about the clinical importance of STIs among HIV-positive patients. Last, it is crucial to change financial incentives that discourage nucleic acid amplification testing for rectal chlamydia and gonorrhea infections.

[CLINICO-MORPHOLOGICAL FEATURES OF FEMALE URETHRAL MEATUS POLYPS].

The aim of the study was to establish the clinical and morphological characteristics of female urethral polyps including cases with concomitant sexually transmitted infections. A total of 150 women were enrolled in the study. The evaluation of microcirculatory changes, morphological parameters and immunogram indices of urethral polyps were carried out. The most common infectious agent in patients with urethral polyps was Ureaplasma urealyticum. In those cases predominance of inflammatory symptoms and elevated levels of serum proinflammatory cytokines were identified. It is found that the pronounced inflammatory reaction leads to an increase in the relative area of the subepithelial microvascular bed and the cellular elements population of lamina mucosa propria, as well as to the relative predominance of congestive forms of microcirculation disturbances according to the laser Doppler flowmetry.

[Sexually transmitted infections as a cause for solid rectal pseudo tumors]. / Sexuell übertragbare Infektionen als Ursache von solide imponierenden Pseudotumoren des Rektums.

Two cases of symptomatic proctitis with rectal tumors suspicious for malignancy are presented. A florid regenerative proctitis was shown in the histological examination. In both cases a sexually transmitted infection (STI) was causing the symptoms. In rare cases STIs present as pseudo tumors mimicking malignancy in clinical examination and endoscopic/radiological analysis. A close collaboration between gastroenterologist and pathologist is necessary for a correct diagnosis and to prevent unnecessary surgical treatment.

Chlamydia trachomatis related knowledge and practices in medical practioners--a survey.

INTRODUCTION: Chlamydia trachomatis is a frequently encountered condition by general physicians, urologists and infectious diseases specialists. It can affect both genders and causes significant morbidity if not treated properly and promptly. In addition, it can cause ophthalmia neonatorum, which manifests as neonatal conjunctivitis in the newborns. METHODOLOGY: The data was collected from fourteen tertiary care hospitals in two provinces of Pakistan during the time period of four months (September-December 2013). Inclusion criteria included all medical practitioners working at those hospitals and there were no limitations of age and gender to participate. The participants were approached through email which included a self administered questionnaire. Written consent was obtained from the participants and the study was approved by the ethical committee of all selected hospital. RESULTS: Overall 130 participants participated with a response rate of 65%. Females were 52.3% and males were 47.7%. In the study 17.7% of male and 29.4% of female participants proclaimed that they referred a patient to an infectious disease specialist in case the diagnosis of Chlamydia was dubious. 72.5% of the male and 55.8% of the female medical practitioners indicated that they yield detailed sexual history from the patients with Chlamydia. Regarding inquiring about the drugs history from the patient at risk of STDs, 22.6% male and 35.3% of female participants informed that they took a detailed drug history. Only 1.5% of the female medical practitioners notified Chlamydia to the partner of diseased patient themselves (provider referral). 24% male and 17.6% female participants had an understanding regarding the definite test of diagnosis for sexually transmitted Chlamydia. CONCLUSION: More sexual health skills development is required in medical practitioners working in Pakistan. The major deficient areas are sexual and drug history taking, management of sexually transmitted diseases and partner notification.

Infecciones de transmisión sexual (ITS) en Chile / Sexually transmitted infections (STI) in Chile

Las Infecciones de Transmisión Sexual (ITS) son infecciones causadas por diversos agentes (bacterias, virus, parásitos, protozoos, entre otros) y cuyo mecanismo de transmisión es el contacto sexual: genital, oral o anal, condición que les da su principal característica y que tiene implicancias en la prevención, pues se relaciona directamente con el "comportamiento sexual" del ser humano, y por lo tanto, con un acto de decisión personal. Las ITS son "PROBLEMA DE TODOS" en razón de ser Universales, no respetando razas, sexos, edad, cultura, creencias religiosas, situación socioeconómica, etc. Constituyen aún un importante problema de Salud Pública en todo el mundo a pesar de los esfuerzos por controlarlas y eventualmente erradicarlas como ha sucedido con otras enfermedades infecto contagiosas. Las modernas tecnologías usadas en el diagnóstico de laboratorio permiten identificar con mayor eficiencia los agentes causales, y el desarrollo de nuevos antibióticos permiten tratar con mayor eficacia, interrumpiendo así la transmisión.

Sexually Transmitted Infections (STI) are sexually infections caused for many agents (bacterias, virus, parasites, protozoos, etc.) and where the transmission is the sexual contact, vaginal, anal or oral, condition who give them the principal characteristic. And that have very important implicancies in prevention, because is directed related with sexual behaviour of human being and finally with and act of personal decision. The STI are a problem of all, in reason of being universal, without respect of races, sex, age, culture, religious credences, social economical position, etc. Today are an important problem in public health in all the World in spite the efforts for control and eventually erradicate them in the way who has succeded with others infectious diseases. Moderns technologies used in the laboratory diagnosis allow us identified with more eficcacious the agents and the development of new antibiotics will be the key to treat with more eficciency our patients and by this way close the chain of transmission.

Is the recall of men who have sex with men (MSM) diagnosed as having bacterial sexually transmitted infections (STIs) for re-screening a feasible and effective strategy?

OBJECTIVES: To assess the feasibility and outcomes of recalling men who have sex with men (MSM) diagnosed as having a bacterial sexually transmitted infection (STI) for re-screening. METHODS: This evaluation was conducted from December 2008 for a 9-month period. MSM diagnosed as having a bacterial STI in that period were offered recall for re-screening 3 months after their diagnosis. Re-screening rates and infection incidence were calculated. Differences in baseline characteristics by re-screening status and factors predictive of infection at re-screening were assessed using the Mann-Whitney test, χ(2) test and logistic regression. RESULTS: Of the 337 MSM diagnosed as having a bacterial STI, 301 were offered recall. Of these, 206 (68.4%) re-screened after 3 months, 30 (10%) declined and the remainder did not re-attend despite giving verbal consent. Compared with those not re-screening, those re-screening were less likely to be HIV positive (p=0.001), but there was no difference in baseline risk behaviours. There were 15 diagnoses of bacterial STIs at re-screening (29 per 100 person-year follow-up (pyfu); 95% CI 14.3 to 43.7) and five new HIV diagnoses of whom three had a negative test at baseline, one tested negative 6 months earlier and one never tested. Among those testing at both time points, the HIV incidence was 8.3 per 100 pyfu (95% CI 0.0 to 17.7). CONCLUSIONS: This evaluation demonstrates a 'recall for re-screening' strategy is feasible in terms of high re-screening rates and incidence of new infections diagnosed. Experimental evidence is needed to assess cost-effectiveness and whether it achieves its aim of reducing transmission of STIs and HIV.

[Efficacy of combined physiotherapeutic methods in complex treatment of patients with chronic infectious urethroprostatitis].

The study is aimed at investigation of efficacy and safety of a combined effect of laser therapy and vibromagnetotherapy in complex treatment of patients with chronic urethroprostatitis in the presence of sexually transmitted infection (STI). A total of 35 males aged 20 to 51 years entered the study. They were divided into 3 groups. Group 1 received standard basic therapy, group 2 received basic and laser therapy, group 3 - basic treatment and laser plus vibromagnetotherapy. Effectiveness of the treatment was assessed by the evidence obtained from clinical, bacteriological, device and functional examinations. The results of the treatments were evaluated after 2 weeks of the follow-up. It is shown that patients of groups 2 and 3 achieved more pronounced improvement of clinical and laboratory indices, parameters of basal blood flow. Thus, physiotherapy, added to antibacterial treatment, is safe and effective in the treatment of chronic urethroprostatitis and STI.

Male genital tract chlamydial infection: implications for pathology and infertility.

Chlamydia trachomatis infections are prevalent worldwide, but current research, screening, and treatment are focused on females, with the burden of disease and infertility sequelae considered to be a predominantly female problem. The prevalence of chlamydial infection, however, is similar in males and females. Furthermore, a role for this pathogen in the development of male urethritis, epididymitis, and orchitis is widely accepted. The role of Chlamydia in the development of prostatitis is controversial, but we suggest that Chlamydia is an etiological agent, with incidences of up to 39.5% reported in patients with prostatitis. Infection of the testis and prostate is implicated in a deterioration of sperm, possibly affecting fertility. Chlamydia infections also may affect male fertility by directly damaging the sperm, because sperm parameters, proportion of DNA fragmentation, and acrosome reaction capacity are impaired with chlamydial infection. Furthermore, the proportion of male partners of infertile couples with evidence of a Chlamydia infection is greater than that documented in the general population. An effect of male chlamydial infection on the fertility of the female partner also has been reported. Thus, the need for a vaccine to protect both males and females is proposed. The difficulty arises because the male reproductive tract is an immune-privileged site that can be disrupted, potentially affecting spermatogenesis, if inappropriate inflammatory responses are provoked. Examination of responses to infection in humans and in experimental animal models suggest that an immunoglobulin A-inducing vaccine will be able to target the male reproductive tract effectively while avoiding harmful inflammatory responses that may impair fertility.

Design and analysis of stepped wedge cluster randomized trials.

Cluster randomized trials (CRT) are often used to evaluate therapies or interventions in situations where individual randomization is not possible or not desirable for logistic, financial or ethical reasons. While a significant and rapidly growing body of literature exists on CRTs utilizing a "parallel" design (i.e. I clusters randomized to each treatment), only a few examples of CRTs using crossover designs have been described. In this article we discuss the design and analysis of a particular type of crossover CRT - the stepped wedge - and provide an example of its use.

Examination of the treatment and follow-up care for adolescents who test positive for Chlamydia trachomatis infection.

OBJECTIVE: To document the comprehensive management of Chlamydia trachomatis infections in sexually active 14- to 19-year-old adolescents. DESIGN: A chart review of both paper and electronic records to examine documentation of treatment and follow-up of adolescents who tested positive for C. trachomatis infection. SETTING: Five pediatric clinics of a large northern California health maintenance organization. PARTICIPANTS: Consecutive sample of 122 adolescent girls and boys aged 14 to 19 years who tested positive for C. trachomatis infection beginning May 1, 2001, for 20-month (4 sites) or 4-month (1 site) study periods. MAIN OUTCOME MEASURES: Antibiotic treatment, counseling regarding safer sex, management of patients' partners, screening for other sexually transmitted infections, and retesting for C. trachomatis infection. RESULTS: The median age of participants was 16.9 years. All but 4 teenagers (97%) were treated with appropriate antibiotics. During follow-up, safer-sex counseling was documented for 79% of the patients. Partner management was addressed for 52% of the patients. Only 36% of the patients were tested for other sexually transmitted infections, and 10% received C. trachomatis retesting during the Centers for Disease Control and Prevention-recommended time frame of 3 to 12 months after treatment. Significantly fewer boys than girls received safer-sex counseling (P = .02) and partner management (P = .02). CONCLUSIONS: Most teenagers received appropriate antibiotics, but fewer received other recommended care. The current study highlights important "missed-opportunity" clinical encounters for counseling to address high-risk behaviors, management of partners, detection of other sexually transmitted infections, and retesting for reinfections. Systems to address these gaps in care should be incorporated into the clinical management of adolescents infected with C. trachomatis.

Is it justifiable to perform screening tests for Chlamydia trachomatis in pregnant women?

Worldwide, Chlamydia trachomatis (CT) is the most common sexually transmitted bacteria. The improved understanding of CT pathophysiology in recent years became possible through DNA amplification technique and genome cloning. This paper updates informations on chlamydial infection in pregnant women, its pathophysiology, diagnostic methods, prevention and treatment. There is increasing evidence that Chlamydia trachomatis infection may result in a number of adverse pregnancy outcomes, including early and late abortion, infection of the foetus, stillbirth, premature rupture of membranes, prematurity and postpartum endometritis. Ectopic pregnancy is often associated with a previous tubal chlamydial infection. C. trachomatis infection in newborns may be acquired during pregnancy or during vaginal delivery, and it may result in neonatal conjunctivitis and/or pneumonia. We discuss benefits of early treatment of chlamydial infections in pregnant women and present guidelines for treatment. Screening should lead to early detection and treatment of men and women with chlamydial infection and thereby reduce the incidence of pelvic inflammatory disease, tubal infertility and ectopic pregnancy.

The latest from the IVD industry December 2004. Chlamydia--pathogens that are still often underestimated.

Chlamydiae are bacteria living as intracellular parasites. Contemporary differentiation distinguishes nine species, of which three are relevant to human medicine. Infections with Chlamydia trachomatis are among the most widespread sexually transmitted diseases. Chlamydophila pneumoniae invade the respiratory tract, chlamydophila psittaci is the pathogen of ornithosis. Chlamydial infections frequently progress asymptomatically and hence remain untreated. Serious chronic secondary diseases are the outcome; they are protracted and cost intensive in treatment. Besides the detection of the pathogen, serology plays a vital part in diagnostics. The antibiotic therapy of chlamydial infections involves the application of tetracyclines, macrolides or chinolons. Chlamydophila pneumoniae in particular has become focus of medical interest as one of the causes of arteriosclerosis.

Chlamydia trachomatis infection in adolescents.

C. trachomatis infections remain epidemic among sexually active young women and place these women at risk for major lifelong reproductive morbidity, including tubal infertility and chronic pelvic pain. The prevalence and importance of chlamydial infections among sexually active adolescent and young adult males have yet to be determined. Most recently, a synergistic relationship between risk for STI infections and HIV has been described. More randomized controlled trials need to be done to define this latter relationship. Cost-effectiveness of broad-base screening and treatment in a variety of populations that differ by prevalence, age, gender, and risk for HIV infection has yet to be determined. Finally, researchers are actively pursuing the development of an effective chlamydial vaccine that, in theory, would be given to prepubertal youth before the onset of sexual activity.
